'90 Paint Color Question

I have a '90 XJ thats a metallic beige color. In the '90 FSM, it lists color code HY3 as "Sand Metallic Clear-Coat" which is the only color that makes sense for whats on the vehicle. However, in the 'primary paint' location on the tag on the firewall it reads "PY3" which is not listed in any of the XJ or other 1990 paint codes.

I want to refinish the vehicle soon, and I'd like to figure out what color it is so I can buy the right paint to match the jambs when its all done.

Thanks.
